N0s1

n0s1-mcp

smithery badge

An MCP server that exposes n0s1 secret-scanning capabilities as tools for AI assistants (Claude, Cursor, etc.).

Scan Jira, Confluence, Slack, GitHub, GitLab, Zendesk, Linear, Asana, Wrike, and local filesystems for leaked secrets — directly from your AI workflow.

Quickstart

No install required. Add this to your MCP client config and run via uvx:

{
  "mcpServers": {
    "n0s1": {
      "command": "uvx",
      "args": ["n0s1-mcp"]
    }
  }
}

For Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json
For Claude Code: .claude/mcp.json in your project, or ~/.claude/mcp.json globally.
